I work with Django.  If I have a project that was written with, say
django 1.4, and it works I can leave that code to run in a virtual
environment that uses django 1.4.  Then I can create another
environment for a new project that uses django 1.9.  If I loaded the
new version of django as a system level package, this would break the
first project.
